Like.
You are just cheating yourself out of essential background understanding (which is the really fun part) if you've skipped chapters 1-3... -

PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life."Science" as it relates to thread discussions here does not mean "something that I can plausibly argue is possible based on our current...

PeterDonis replied to the thread Graduate Wavefunction in the context of quantum physics.Sure you have, just not under that name. The Hermite functions are Gaussians with polynomial prefactors--indeed, the zero-order Hermite...
-
PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.Um, sci-fi stories are about "the context of possible engineering" that doesn't currently exist. In our actual science forums like the...

PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.@DaveC426913 did not move this thread to the sci-fi forum. The moderators did, for the reason I gave in post #227 just now. That reason...

PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.To clarify, the moderators reviewed the thread and determined that it belongs better in this forum, since the discussion is not really...

PeterDonis replied to the thread High School True static equilibrium and effects on time.The frame in which you are at rest right now is not inertial. You are stationary in this frame--because you are at rest in the frame...

It is implicit. You picked the single hardest problem in all creation. It stands to reason that any simpler problem will be solved...

Then this - which was the very genesis of everything we have been talking about - makes no sense: This is an ad hom. If I were not a...

PeterDonis replied to the thread Alien life, probabilities, and interstellar propagation of human life.How could you ethically test that?

PeterDonis reacted to gentzen's post in the thread Graduate Wavefunction in the context of quantum physics with Like.
Yes :smile: The Hermite functions are such a Hilbert basis. They are eigenfunctions of the Fourier transform. They are well localized in...

PeterDonis replied to the thread Graduate Wavefunction in the context of quantum physics.Not in the set of square integrable functions, since those functions are not square integrable, as you note: Yes, which means they...

PeterDonis replied to the thread High School True static equilibrium and effects on time."Stationary" is a matter of "kinematics" as you are using the term here. It's just a choice of reference frame. You can do it with any...
